GB was intereested enough in Anna's birth, to insist on a name for her that he felt was more appropriate. Possibly one which he felt came with some connection to him. Yet for the remainder of the time that she lived with her Mom, he lost interest in her. That isn't logical. Unless he was waiting on something (for her to grow enough to leave her mother? for him to find a couple willing to buy her?). And possibly he only appeared to lose interest so that when she eventually was taken, less suspicion would fall on him and GW.
As far as the couple living within a half day of Anna's residence, that might be true if the George's were not involved. But if the George's were involved and Anna was targeted, well prospective parents desparate enough to buy a kid, and willing to kidnap her to get her- they would come a long way to get her, if they were aware of her. To this day, people have been known to travel to other states or even to other countries to pick up an adoptive child.
IMO, if they were going to be involved in the kidnapping of the child- I would think the farther away they came from, the better for them.
I guess that is why the religion aspect of this makes so much sense to me. If we are correct in the religion- it was based in Canada. GB may have had contacts within it. (or he may not, it could have simply been the fact that learned of the religion and it appealed to him, and he "studied" it, and practiced it totally on his own). But if he did actually attend services for it, he may have developed some contact with those in Canada. Thus he may found someone with an interest in getting a child however they could. Or they could have been convinced that they were "rescuing" this poor child, that her father was so concerned about. (Anna's mom, this isn't a slight, only trying to think how they may have presented it to a prospective couple).
I would be interested to know if either of the George's ever called Anna's Mom out of the blue, odd type calls. Maybe to try to convince them to get into an "investment" or talk about the religion or just some excuse to call. In those circumstances, to change the subject Mom might start talking about Anna, just to change the subject or out of outrage that they called and didn't ask about her. The calls may have been to get info on the child, the not asking first, may have been to further the appearance of disinterest.
I would also suspect that there may have been an occasional drive by her school or other place she might have been, just to see her.
I would also like to know if either or both the George's attended church services, and if they ever travelled. Maybe to Canada.
